Crafting mechanics & physics engine

χcraft is an open-world exploration game in the lineage of No Man's Sky and Palworld, with one structural break from the genre: crafting is governed by a physics, not a database.

1Ontology: modes, patterns, instances

Modes are the primitive alphabet: the Standard Model particle set, imported from real physics data. A mode carries immutable quantum numbers, a real lifetime, a real cosmic abundance, a symmetry classification, and a generation index. Modes are the only authored content in the entire matter system.

Patterns are compositions of modes — or of other patterns, because composition is recursive. A pattern is content-addressed by its component multiset plus its binding-pathway class. Patterns carry no authored stats whatsoever.

Instances are placed occurrences of a pattern in the world. They decay stochastically, and their live population is what the Census counts.

2The five axes at runtime

RehearsalLog-scaled age since the pattern's first cut in the Ledger. Primitives inherit real theorization dates.
Half-lifeReal lifetimes for primitives; observed decay statistics for composed patterns. The engine measures, it does not assume.
Census shareLive fraction of the world's matter-energy budget held by this pattern's instances.
Binding standingsubstrate (χ) < hosted < composite < fundamental < gauge. Composites inherit the floor of their components, lifted by coherent binding.
LineageDistance from first-generation modes. A top-quark verse carries third-generation cost no pathway can fully discharge.

3Da Xencula: the cut

Stage 1 — hard conservation. Charge, colour neutrality, baryon and lepton number, energy budget. These are the only inviolable rules in the game, and they are the real ones. A proposal that fails stage 1 doesn't fizzle; it is simply not a sentence the universe parses.

Stage 2 — the coherence functional. Χ ≥ 0.62 and the verse cuts: a new pattern enters the Ledger and the census updates. Between 0.38 and 0.62 it resonates — it rings but will not hold, and a residue event is logged to the anomaly engine. Below that, clean failure with pathway-dependent loss.

That residue is what we understand gravity to be. A ringing verse sheds what it couldn't carry — the fraction of coherence that failed to keep up — and that shed settles into the world as mass. Gravity is not a force that pulls; it is the settling of what couldn't keep up. residue = (1 − efficiency) × intensity × gradient × dt. Every incoherent binding thickens the world.

4Pathway primacy: crafting as performance

Ramp — slow monotone sweep. Highest I-register, deepest written τₖ, slowest. Patience is a material property of the result.

Jump — discontinuous slam. Fast and cheap; the product cuts shallow. Jump-crafting makes ammunition; ramp-crafting makes heirlooms.

Ring — oscillatory approach. Hitting the resonance window multiplies I and can lift a composition over Χ_cut that no ramp could afford; missing it dumps residue.

Because the pathway is part of the pattern hash, performances are the tradeable knowledge object. The recipe alone underdetermines the object — the wiki-solves-everything failure mode is structurally impossible.

5The world: open_space( ) and η_bind

The world is permeated by the χ substrate carrying a scalar field η_bind ∈ [0,1]. High-η shorelines are matter-dense and forgiving, but their hosting slots are full. Low-η regions are open_space( ): ordinary cuts get harder, but each unit of refusal opens hosting capacity at a TMI bonus.

The frontier direction of the map is not far away — it is down the η gradient, into space that refuses harder and hosts more. Players prospect the halo with gravitational instruments: dark matter as terrain, surveying as reading the mass the light doesn't account for.

6The core loop

The ≈⅔ partition is a systemic constant: roughly 65% of a deep verse's budget must route into bound, localized form, ~35% stays fluid. No perfect extraction, ever — every gain writes something back into the world.

  1. Prospect — read the halo, find open_space( ), claim hosting capacity.
  2. Accumulate — gather overflow: high-τₖ material whose channel cannot carry its mass budget.
  3. Compel — perform the crossing at the QCD shoreline; ramp, jump, or ring.
  4. Host — land the product in your claimed slots; hosted verses accrue rehearsal and census share.
  5. Recompose — the census shifts, TMIs drift, new tensions accumulate.

7The anomaly engine

The engine maintains an expectation model for every process the current catalog can express. When observed rates sit persistently off prediction — same direction, across regions, across epochs — the residual is promoted to an Anomaly and begins accruing its own τₖ-mass. Age and cross-confirmation make an anomaly heavier, not staler. Because residue is gravity, the heaviest anomaly in the catalog is also the gravest heap of mass in the world — the Black Sun.

Resolution is compositional: somewhere in pattern-space is a missing mode that re-fits the observations. Breadth is depth — a candidate keying several tensions at once earns a symmetry-standing bonus of 0.85 that single-anomaly patches cannot reach. The engine structurally rewards unification over epicycles.

8Biometal fusion: the win–win endgame

A biometal is not a metal biology consumes; it is a mineral τₖ-core and a living lineage agreeing to keep each other. Surplus exists only on the hosted pathway: TMI(core ⊕ cage, ramped) > TMI(core) + TMI(cage), while jump-binding a bare ion is the extractive limit with no surplus at all.

Heme iron, the [4Fe-4S] cubane, chlorophyll's magnesium, the Mn₄CaO₅ ratchet, FeMoco, cobalamin's Co–C bond, the zinc finger, biologically-sized magnetite — none of these are authored items. They are attractors the physics should rediscover. If players re-derive photosynthesis's water-splitting ratchet without the game ever containing an entry for it, pillar one is proven.

9The CDT substrate: rendering a world that keeps score

The abstract physics above needs a rendering engine that is itself coherent with it. The CDT (Coherence Data Type) substrate provides one: instead of discrete block states and lookup tables, every voxel coordinate holds a localized complex field — Ψ(x) = Σ Aₖ·e^{iθₖ}. Amplitude A is physical density and structural permanence; phase θ is material state (0 reads as solid crystal, π/2 as fluid, π as vapor/field energy); and τₖ is the binding coefficient — higher τₖ lowers decay and stabilizes the structure against entropic degradation. It is the same τₖ the TMI kernel writes on a ramp.

Terraforming never collides. When two players alter the same region there are no overwrite locks or merge counters: updates superpose by field addition, Ψ_final = Ψ_A + Ψ_B. Aligned phases (Δθ ≈ 0) reinforce — matter solidifies faster, shared building literally hardens. Opposed phases cancel mass into hollow cavities or vapor without destruction. Consensus geometry is what renders: the maximum spectral density of the field becomes the visible world, while alternative builds remain in superposition, reachable if the observer shifts local frequency.

Because chunks persist as phase-indexed field matrices rather than block IDs, multiple realities coexist on identical coordinates. A player tuned to θ = 0 walks a solid glass bridge across a volume where a player at π/2 swims an open aquifer. The world's deepest structures — residue heaps, anomaly sites, the Black Sun's deficit — are the same field read at phases ordinary observation never visits.

This also settles the economics in-engine. Value composes in real time as Yield = Δt × Quality × τₖ: presence and phase-locked building reward both player and world, not grinding. Creator commitment (baseline focus units stabilizing a dimension's ruleset) and attention-futures let players invest directly in the persistence of places — the census axis made spendable.
